Well known and respected developer chpwn has finally released first legal Siri port to public for older generation iOS devices. Dubbed as Spire, the port allows iPhone 4, iPhone 3GS, iPod touch 4G/3G and first-gen iPad users, jailbroken on iOS 5, to run Siri, which has official been available only for iPhone 4S users.

Available for free on Cydia right now, the download comes in at around 100mb in size as it uses a new method to obtain all the necessary files legally directly from Apple’s servers.

There is however a catch to it. It is not as easy to get it running as it sounds. You will need to have your own Siri proxy setup, and an iPhone 4S for authentication to get it running on your older-gen iOS device.

To install Spire package, simply head over to Cydia, search for “Spire”, and install it. You don’t need to add any new repo as it is available on Cydia’s default BigBoss repository.

You will obviously need to have a jailbroken device to get it to work. For jailbreaking iOS 5 tethered using Redsn0w, you can follow our complete step by step guide posted here, or here if you want to use Sn0wbreeze on Windows. Since jailbreak on iOS 5 is currently limited to tethered boot only, you can install ‘SemiTether’ patch (instructions here) from Cydia to make your jailbreak semi-tethered on iOS 5. For those of you on iOS 5.0.1 can follow our instructions posted here on how to jailbreak using Redsn0w, or here using Ac1dSn0w (instructions with Ac1dSn0w Beta 2 here), or here using Sn0wbreeze.
